Electronic product shell mold is a special tool used to manufacture electronic product shell, which can be accurately molded according to product design requirements and specifications. The following Dongguan Shuangyu plastic mold will introduce several common types of electronic product shell molds and their production methods.
1. Plastic injection mold.
Plastic injection molds are one of the most common types of molds used to make electronics enclosures. It consists of two main parts: the upper die and the lower die. The upper and lower dies work together to inject the molten plastic material into the mold cavity by heating and injection molding, and then cool it to form it to finally obtain the desired shell shape. The plastic injection mold making process includes the following steps:
Design the mold structure: determine the structure, size and shape of the mold according to the product design requirements, and carry out the 3D design of the mold.
Make the mold core and mold cavity: According to the design drawings, use machining processes (such as CNC machining, wire cutting, etc.) to make the mold core and mold cavity. High-hardness steel materials are usually used to ensure the wear resistance and longevity of the mold.
Machining mold parts: further processing of the mold core and mold cavity, such as milling, drilling, grinding, etc., to ensure the accuracy and quality of the mold.
Assemble the mold: Assemble the mold core and mold cavity together, and debug and calibrate to ensure the accuracy and normal operation of the mold.
Commissioning and testing: After the mold is completed, the commissioning and testing of the injection molding machine is carried out to determine whether the injection molding process parameters and shell molding effect of the mold meet the requirements.
2. Metal stamping die.
Metal stamping dies are often used to make metal housings or metal parts. It consists of an upper die, a lower die and a mold holder. The sheet metal is placed in a mold, and the metal sheet is formed by cutting, bending, and stretching on the mold by the force of the press. The metal stamping die making process includes the following steps:
Design the mold structure: determine the structure, size and shape of the mold according to the product design requirements, and carry out the 3D design of the mold.
Make the mold core and mold cavity: According to the design drawings, use mechanical processing processes (such as milling, drilling, wire cutting, etc.) to make the mold core and mold cavity. Tool steels or alloy steels with high hardness are usually used to ensure the wear resistance and longevity of the mold.
Machining mold parts: further processing of the mold core and mold cavity, such as heat treatment, grinding, etc., to ensure the precision and quality of the mold.
Assemble the mold: Assemble the mold core, mold cavity and mold seat together, and debug and calibrate to ensure the accuracy and normal operation of the mold.
Commissioning and testing: After the mold is completed, the stamping machine is used for debugging and testing to determine whether the stamping process parameters and forming effect of the mold meet the requirements.
3. Casting mold.
Casting molds are used in the casting process of manufacturing electronics enclosures or components. Common casting methods include pressure casting, gravity casting, and sand casting. The casting mold making process includes the following steps:
Design the mold structure: determine the structure, size and shape of the mold according to the product design requirements, and carry out the 3D design of the mold.
Make the mold core and mold cavity: according to the design drawings, use mechanical processing processes (such as CNC machining, EDM, etc.) to make the mold core and mold cavity. High-temperature wear-resistant materials such as steel, iron, etc., are usually used.
Machining mold parts: further processing and surface treatment of the mold core and mold cavity to ensure the accuracy and quality of the mold.
Assemble the mold: Assemble the mold core and mold cavity together, and debug and calibrate to ensure the accuracy and normal operation of the mold.
Commissioning and testing: After the mold is completed, the commissioning and testing of the casting equipment is carried out to determine whether the casting process parameters and forming effect of the mold meet the requirements.
Electronic product shell molds can choose different production methods according to different product needs, including plastic injection molds, metal stamping molds and casting molds. Making these molds requires multiple steps such as design, component processing, assembly, commissioning, and testing to ensure the accuracy, quality, and reliability of the molds. These molds provide an efficient, precise, and repeatable production process for the manufacture of electronics enclosures.
